I don't have standpipe. Only a dirt spillway. I don't have any way to test temps under water or at thermocline. I just have a floating pool thermometer. Same one I have been using for several years. We are supposed to have a tropical storm next weekend so I may just wait a little longer before I fire up the aeriation. My deepest part is only between 11-12 foot.

Dear Alcohol, We had a deal where you would make me funnier, smarter, and a better dancer... I saw the video... We need to talk.
